We've just been out looking for rental properties today in Wellington (where we've decided we'd like to settle for the mo!) and you can expect to pay from $300 - $350 per week for a 1 bed flat in the centre, or around $250 - $300 per week for a 2/3 bed house in the subarbs (15 mins drive into the CBD).

Any more help I can give, let me know!
